On the West. By the meridian of 95° east longitude. 
In the event of the Canadian or Australian Governments 
sending their vessels to another part of the British Empire, 
notice is to be given to the British Admiralty, and if they 
desire to send ships to foreign ports the concurrence of the 
Imperial Government is to be obtained, in order that the
